CLAMP, ron BROKEN srnnves.

To all whom it may concern:

' Be it known that I, SAMUEL H. BRADY, a

citizen of the United States, residing at Reno,in the county of Washoe and State of Nevada, have invented new and useful Improvements in Clamps for Broken Springs, of which the following is a specificatlon.

This invention relates to clamps for use on broken vehicle springs and the principal object of the invention is to provide a palr of clamping members 'for clamping the broken ends of the leaves to the body of the sprin Another object of the invention is to provide means for adjusting the clamps to suit different sizes of springs.

This invention also consists in certain other 'features of construction and in the combination and arrangement of the several parts, to be hereinafter fullydescribed, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a view showing the device in use on a broken spring.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a perspective view of one of the clamping plates.

Fig. 4 is a view of one of the plate engaging members or washers.

Fig. 5 is a view of the plate for holding the two clamps together.

Fig. 6 is a 'detail view of a modification.

Fig. 7 is a detail view of another modification.

As shown in these views the device consistsof a pair of clamps A and B for clamping the leaves adjacent the break to the body of the spring. Each of these clamps consists of an upper and lower clamping plate 1 which extend across the spring, the washers 2 and the bolts 3. Each plate is provided with a longitudinally extending slot 4 divided into two parts by the central portion 5. The inner face of each plate is smooth to engage the spring, while the outer face is corrugated, as at 6, the corrugations being omitted from the central part 5. The washers 2 are each of elongated form and has one face corrugated as at 7 to engage the corrugations 6 of the clamping plates. Each Patented July 12, 1921.

Application filed November 1, 1919. SerialNo. 334,915.

washer is also provided with the centrally arranged hole 8 for receiving the bolts 3.

. The bolts are passed through the holes in thewashers and the slots in the clamping plates and said washers and bolts are adjusted on the clamping plates to bring the bolts against the edges of the spring, as shown in Fig. 2. The nuts 9 are then tightened on the bolts to lock the washers on the plates.

As shown in Fig. 1 the clamps are placed on each side of the break, shown at C, so as to clamp the broken leaves adjacent the break to the body of the spring.

In order to prevent the clamps from separating I provide a plate 10 having its ends curved upwardly as at 11. This plate is placed on the top of the spring and the upper clamping 'plates are placed on this plate adjacent the curved ends thereof so that said ends will prevent the clamping plates from moving apart.

If the break should be in the middle of the spring between the clips D this plate would be omitted and the clamps located on each side of the web of axle E.

I form a loop 12 at one end of the plate 10 so that if the top leaf of the spring should break near its end this plate could be substituted 'for the end of the leaf and the loop 12 take the place of the end loop of the spring.

The corrugations may be made of rounded form, such as shown at 6 in Fig. 6, instead of the angle form shown in the preceding figures or they may be made of square 'formation as shown at 6 in Fig. 7. It will of course be understood that the corrugations in the washers would be made to match.

The clamps may be easily and quickly placed on the broken spring and due to the adjustability of the clamps said clamps may be used on springs of different widths. The device as a whole may be carried in a tool box as the parts will occupy but little space.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A clamp of the class described comprising two pairs of clamping plates, each plate having a air of longitudinally extending slots thereln, the slots being separated at their inner ends and one face-of each plate being corrugated, a pair of bolts connecting each, pair of plates together, said bolts passing through the slots and elongated washer bars through which the bolts pass, each bar having one face corrugated to engage the corrugations in the plate.

2. clamping device of the class described comprising two pairs of clamping plateseach having a pair of longitudinally being corrugated to interlock with each othe'r,a top plate upon which-"the upper slotted plates "rest, vsaid top plate having projections at it endsand one projection beformed in the'shape of an eye.

slots in said plates elongated washer plates ,for said bolts, saidvplates and washer plates i1 testimony whereof I afiix my signature.
